The actual :: underdevelopment of the gas pump and gas pump for gas pumps is limited in number, they are limited in length and in length, and there are pipes, which is from mass

in the bath pestle. The magnitude of the pump’s damedepdev damages it (this leads to an uneven distribution of the pressure pulse V on the metal surface. In the case of pressure transmission, Meimjtn is sprayed in the upper free cavity of the pipe, and the pump fails.

B1: this is not the only thing that the necessary intuitiveness of the rewinding of m & racks in large-scale furnace with a large tank capacity in HomofOix is ensured without setting the required number of pumps.

It’s interesting that at 3amicuMocmi from the direction of the jet gas stream relative to the surface of the melt in the tube, the cycle can’t ignore the unevenness of the distribution of the impulse of the signal on the Mermj--, as a result of which the pump efficiency and efficiency are removed.
